MACHINE FOR COMPRESSING HEEIS.

T 0 aZZ whom t may concern.'

Be it known that I, TILLIAM R. BARCLAY, a citizen of the United States, residing at Leicester, Leicestershire, England, have invented certain Improvements in Machines for Compressing Heels, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for compressing` sole leather blanks for boots or shoes. The machine constituting the speciiic embodiment of the invention hereinafter described and illustrated is adapted for compressing a blank having the marginal portion of its face located out of the plane of the interior portion of the face. An example of this kind of a blank is a heel having a marginal recess in its tread face formed to receive a metal heel tip of horseshoe shape.

The invention is shown applied to a machine of the type in which the bottom of the mold cavity is formed by a device vertically movable to remove the heel from said cavity.

An important feature of the invention consists in a movable device of this nature constructed to accommodate a blank having the marginal portion of its face out of the plane of the interior portion thereof. According to the preferred construction the device is so formed and arranged that when in compressing position at the bottom of the mold cavity its marginal portion is at a different level from its central portion and when raised in said cavity all portions 'of its upper surface are atsubstantially the same level. rl`he device shown comprises a plurality of sections which are arranged for automatic relative movement during the vertical movement of said device.

A further feature of the invention consists in arranging the marginal sections which fill the marginal recess in the heel for movement relatively to the central section in a horizontal plane. lWith this arrangement the marginal sections may be somewhat removed from the central section when the heel to be compressed is placed upon the device, thus permitting the central raised portion upon the .tread surface of the heel to readily descend into position Specification of Letters Patent.

the central section by a spring after the dies release the heel.

@ther features of the invention will be hereinafter described and referred to in the appended claims. :Inthe drawings,-Figure l is a view in plan with parts in horizontal section of a portion of a heel compressing machine accoi-ding to the present invention; F ig. 2 is a vertical sectional view of the machine illustrated in Fig. l; Fig. y3 is a View similar to F ig. 2 showing the position of the parts while the pressure is applied to the heel.

The compressing machine to which the present invention is shown applied is of the type of that illustrated in United States Letters Patent No. 776,875 dated December G, 1904, to Tripp, to which referencejmay be had for a complete disclosure of parts of the machine not directly related to the present invention.

Referring to the drawings,l the reference numeral 1 indicates the vertically movable head of the compressing machine and 2 the stationary follower which has engagament with the heel-seat surface of the'heel. Side dies 4; `are mounted upon the head for horizontal. movement thereon, as is fully eX- plained in said patent, and a breast die 6 is forced toward and from the heel in the movement of the sidedies 4:.

rEhe head l is provided with a vertical bore beneath the mold cavity, receiving a plunger 8 which is automatically raised and lowered relatively to the head. The plunger S carries upon its upper end a central flat f section l0 of the contour shown in Fig. l. ln the position of the parts shown in F ig. 3 the central section 10 rests upon the head l and supports the central portion of the heel which constitutes the filler for the horseshoe-shaped tip to be afterward applied to the heel. Two marginal sections 12, 14, are arranged between the central section 10 and the side dies 4. The marginal sections 12, 14 are connected at the rear end of the mold cavity by a pin 16 headed at each end and received in alined bores formed in said marginal sections. The pin 16, as will be obvious, limits movement of the marginal sections away from the central section. A spring 18 is arranged about the pin 1.6 in recesses formed in the adjacent faces of the marginal sections to move said marginal sections apart. The central section 10 is also provided with spring-pressed plugs 20 engaging the marginal sections at different points in their length for the purpose of moving said sections away from the central section.

The marginal sections 14 are provided at intervals in their length with recesses 22 extending from the bottom of the sections to a point short of the upper surface of the section a distance slightly greater than the thickness of the filler piece on the heel to be compressed. ril`he recesses 22 are entered by laterally projecting pins 24 upon the central section 10.

Referring to Fig. 3, while the mold is closed upon the heel the marginal sections 12, 14 rest upon the head 1 and their upper ends lill the recess in the heel in which is subsequently placed the horseshoe-shaped heel tip. lWhen the plunger 8 is raised after the heel is released by the dies, the marginal sections are moved away from the central section 10 by the springs referred to, and thereupon descend relatively to the central section until they rest upon the Lipper faces of the pins 24. rlhe pins 24 are of such a height that when the marginal sections rest thereon the upper surface of said sections is substantially level with the top of the central section 10, as is indicated in Fig. 2. 1t will be seen that in the position of the parts shown in Fig. 2 the heel rests upon a surface which offers no obstruction to horizontal sliding movement of the heel out of the machine. The removal of the heel from the position shown in F ig. 1 may be accomplished by ejecting mechanism such as is shown and described in the Letters Fatent referred to.

lit will be seen that while the plunger 8 is in its raised position the marginal sections 12, 14 are slightly removed from the central section so that when the central section 10 descends below the level of the niarginal portions the bottom lift of the heel may readily descend into position between the marginal sections. ln the closing movement of the marginal sections effected by the side dies, this bottom lift or follower is compressed laterally so that a marginal rerecess in the heel of a predetermined size is insured.

Having described my invention, what l meseta claim as new and desire to secure by Letters Patent of the United States is 1. 1n a machine for compressing heels, a device arranged to form the bottom of a mold cavity and constructed to be raised in the cavity to remove a compressed heel therefrom, said device comprising a plurality of sections arranged to lie at dii'ferent levels in the compressing position of the device and to lie at substantially the same level in the raised position of the device.

2. In a machine of the class described, a compressing member for engaging and eX- erti-ng pressure upon the face of a blank, said member comprising a central compressing portion 10, and a surrounding portion 12, 14, said portions being relatively movable and lying wholly at distinctly different elevations when in pressure exerting position. y
